Low Energy Solutions for Drinking Water
Production by a Revival of Electrodialysis
Systems

Challenge
The balance between drinking water demand and availability
has reached a critical level in many regions of the world.
Factors such as climate change and water over-abstraction
are currently exacerbating the water stress of almost one
billion people worldwide who worry about obtaining enough
water daily. With seawater making up 97.5% of the worlds
water resources, low energy desalination solutions are
crucial in providing sufficient levels of good quality
drinking water for the growing world population.

Project ObjectivesREvivED water aims to contribute to overcoming
the drinking water challenge by establishing
ElectroDialysis (ED) as the new standard
for desalination of seawater. The goal is
to produce safe, affordable and cost-competitive
drinking water with significantly reduced
energy consumption compared to state-of-the-art
reverse osmosis (RO) technology. The REvivED
water project will focus on developing several
new innovative ElectroDialysis systems and
assessing them in different real environments,
ranging from brackish water desalination
to industrial-scale seawater desalination.

already developed around the world.

Expected Results

Development of new innovative ED systems
based on Reverse ED (RED) and ED components
(membrane, electrodes, stacks) for water
desalination applications to significantly
reduce their energy consumption compared
to current state-of-the-art energy technologies.

Assessment of several pilot ED systems
in different real environments.

Sustainable provision of safe and affordable
drinking water all over the world, covering
applications ranging from large industrialised
plants to small, stand-alone systems for
developing countries.
